I. Background and purpose of the standard

YBB00382003-2015 "Tear-off aluminum cap for oral liquid bottles" is one of the important standards for drug packaging in the Pharmacopoeia, which aims to standardize the mechanical properties and performance of tear-off aluminum caps for oral liquid bottles. Among them, the tear-off force test is one of the core projects. Through scientific mechanical testing methods, it is ensured that the aluminum cap has the following characteristics in actual use:

 

1). Moderate opening force: neither too large (to avoid users opening with effort) nor too small (to prevent accidental opening during transportation or storage).

2). Stability and safety: No breakage during the tearing process to ensure the sealing of the drug.

3). User experience optimization: Ensure a smooth opening process to avoid burrs or scratches.

 

II. Core requirements and processes of the test

 

1. Force range

The tear-off force needs to be controlled between 5.0~15.0N, which can ensure that users can open it easily and avoid accidental falling off during transportation.

The test needs to be carried out in a constant temperature and humidity environment of 23℃±2℃ and 50%±5% humidity to ensure stable material performance.

 

2. Test parameter setting

Tensile angle: 90°, simulating real tearing action;

Line speed: 10 mm/s±2 mm/s, to avoid speed deviation affecting the results;

Sample preparation: standard samples with cutting width of 12.5 mm and gauge length of 50 mm are used to ensure test consistency.

 

3. Test judgment criteria

If the sample breaks in the middle, it is considered an invalid experiment and needs to be resampled;

The results must meet the standard force range, and the tearing process must be smooth without burrs or scratches.

 

III. Advantages of Link Testing Instruments
